BBAKEOPERATING SHAFT AND ITS CONNECTION AND HOUNTINGu Application ledOctober 21, 1926. Serial No. 143,099.

My invention relates to improvements in brake operating shafts and theirconnections and to improvements in the mounting and the lubricationthereof.

The object is to provide an improved brake operating shaft provided witha mounting of an improved design and with suitable connections, all ofsimple, c icient construction,l so arranged as to provide a receptaclefor lubricant having communicating outlets leading to the connections onthe shaft and to the shaft mounting to lubricate the same during theoperation of the shaft and its connections.

I have shown my invention as embodied in a brake operating shaft on amotor vehicle chassis of the usual type and provided with connectionsleading to brake structures associated with each of the traction wheelsof the vehicle.

Other advantageous objects and meritor ious features of my improvementwill more fully appear from the following description of the inventionshown in the accompanying drawings and from the claims.

In the drawings:

Fig. l is a plan of a vehicle chassis provided With my invention. Y

Fig. 2 is a vertical sectional view through the operating shaft taken onthe line 2 2 of Fig. 1.

I have shown in the drawing the chassis of a common type of four-wheelroad vehicle in which the side frame members 10 are of channelconstruction as shown in Fig. 2 and the vehicle is supported at each endby a pair of road wheels 12, each of which wheels may be provided with abrake 14 havinga connection 16 which leads `to an arm 18 mounted upon abrake o erating shaft 20.

The brake operating s aft 20 is hollow as shown in Fig. 2. A pluralityof arms 18 are fixed thereon, as illustrated. These arms have bearings22 within which a part of an r operating connection is mounted. Each arm1s providedwith a lubricant passageway 24 leading vfrom the bearing 22to the interior of the shaft 20 so that lubricant may pass from theinterior of the shaft to the bearing.

A plug 26 is fixed in each end of the shafbt, This plug extends beyondthe end of 'the shaft as shown in Fig. 2. A bearing socket 28 is mountedupon each side frame member 10 within the channel thereof and the hollow.shaft 20 is positioned between these bearing sockets and the projectingends of plugs 26 are mounted within the sockets 28 so that the shaft issupported thereby for rotatable oscillation. Each (plug. 26 is providedwith an angularly exten ing passageway 30 which leads from the interiorof the shaft to the side wall of the bearing socket to distributelubricant thereover. The shaft is provided '33 and its operatingconnections are moved, vlubricant asses from its interior to thebearings to lubricate them.

The plug closures at each end' of the shaft also serve as bearingswithin vthe socket connections which support the shaft and formconvenient and suitable mountings for a shaft lubricated in thisparticular fashion.

v What I claim is:

l. vA vehicle chassis provided with opposed channeled side framemembers, a pa1r of oppositely disposed bearin sockets carried therebyone mounted within the channel of one side frame member and the othermounted within the channel ofthe other side frame member, a hollowtubular shaft positioned between said sockets with its ends arranged oposite the ends of the sockets, a closure p ug secured withineach end ofthe shaft and extending therebeyond and received within the adjacentsocket forming a l sup orting bearing Within the socket for the sha t;each plug providedvwith a lubricant passageway extending from theinterior of f the shaft through the plug to the side wall of the socket.

2. A vehicle chassis provided with opposed channeled side frame members,a pair of oppositely disposed bearing sockets` carried thereb onemounted within the channel of one si e frame member and the othermounted within the channel of the other side frame member, a hollowtubular shaft positioned between said sockets with its 'ends a1'- rangedopposite the ends of the sockets, a closure plug secured Within each endof the shaft and extendingr therebeyond and received Within the adjacentsocket forming a sup orting bearing within the socket for the sha t;each plug provided with a lubricant passageway extending from theinterior of the shaft through the plug to the side Wall 10 of thesocket; an arm mounted on the shaft having a bearing at its outer endand rovided with a lubricant passageway extent ing lengthwisetherethrough, said shaft provided With a lubricant passagewayregistering With the passageway through the arm and leading into theinterior of the shaft.

In testimony whereof, l, ROY S. SANDroRn, sign this specification.

RY S. SANFRD.
